The television ad war in Arkansas' Senate race heated up Wednesday, with Democratic U.S. Sen. Mark Pryor and a conservative group spending hundreds of thousands of dollars on new spots airing statewide this week.

Pryor's campaign on Wednesday unveiled two new 30-second ads targeting Republican rival and U.S. Rep. Tom Cotton. The spots will begin airing Thursday and are part of a six-figure ad buy that criticize Cotton for supporting a plan to turn Medicare into a voucher-like system for future beneficiaries.

Americans for Prosperity, a conservative group backed by billionaire brothers Charles and David Koch, announced it would begin airing a spot statewide criticizing Pryor for supporting the federal health-care overhaul. The group said it's spending $606,000 to run the 30-second spot starting Thursday.

You need to read about the Kochs and their history of pollution and bad behavior. These people only care about feathering their nests. They are just about the worst robber barons in the history of capitalism. Any politician whom they favor needs to be shown the door.

pop like i said whats the diff?obozo has bad behavior,polluted our nation,and feathered his nest.while you can often find pryor in bed with him we are the ones getting screwed.atleast koch bro have a clue about economics while obozo seems to not have a clue about much of nothing.

If what the Koch brothers or anyone else says is true, what's the problem?.Pryor is running scared like no pol I have ever seen. He and Mary Landrieu almost broke their necks racing to see which could "encourage" BH Obama to approve the Keystone Pipeline first. And surprise, surprise, surprise, Pryor and Landrieu are both running for re-election from state's that fully understand the destructive agenda of the BH Obama regime.

The Koch brothers father was a John Bircher and they are following in his footsteps only the Citizens United ruling is allowing them to pollute our politics in ways their father could only dream about.

pop,obozo only cares about his agenda.google him and read about his pollution.pryor is appearing to be breaking ties with obozo but thats only because he is up for re election and obozo has a low approval rating in arkansas.
